Overall survival by patient. A) point estimates from single-arm pooled analyses with 95% CIs, B) multivariable metaregressions,^a 95% CIs, and univariable meta-regression significance, C) point estimates from single-arm pooled analyses with 95% CIs for studies with MINORS score of 7 or above and D) point estimates from single-arm pooled analyses with 95% CIs for patients with pulmonary metastases from CRC, RCC, or sarcoma. ^a Multivariable meta-regression adjusted for the following covariates: average age, % male, average tumor size and number, study design (retrospective versus prospective), geographic region (North America, Europe, international, Australia, and Asia as the reference group), and imaging method for LTP assessment (CT versus CT and/or FDG-PET/PETCT). Abbreviations: CI = confidence interval; CRC = colorectal carcinoma; CT = computed tomography; FDG = fluorodeoxyglucose; IGTA = image-guided thermal ablation; ORs = odds ratios; OS = overall survival; ref. = reference group; PET = positron emission tomography; RCC = renal cell carcinoma; SBRT = stereotactic body radiation therapy
